I am printing a model for an orthotic using a newly acquired X1C printer with a 0.4mm nozzle. These kinds of prints have been a piece of cake for my Prusa MK3. It’s high-quality addnorth PLA, settings are 0.2mm “strength” (also have tried standard), 4 wall loops, 25% grid infill.

Not only does the printer fail mid-print and spaghetti out, but the walls are thin and brittle, it basically crumbles when you touch it. The other day i was printing nylon but a model that had 100% walls, it looked structurally sound but spaghettied out mid-print.

Is this firmware, slicer (bambu studio) or hardware related?

This is a partial nozzle blockage/clog.

Do a couple of cold pulls to clear it and check how clean your spool looks.

Respooling filament for the AMS can introduce a lot of dust onto the filament.

Download and install OrcaSlicer and run the calibrations for your filament.

Use a different infill, cubic.

Up your nozzle temp - which may come from the Orca Slicer calibrations.

I’ve had similar issues before I’ve calibrated printer settings for my filament. Even though print finished successfully, layer adhesion was very poor. In my case increasing hotend temp by 5 degrees and lowering cooling from 100% to 70% resulted in much print.

My X1C has badly calibrated hotend temperature sensor, it’s showing 5 degrees C higher nozzle temperature than bed temp, even though printer has been turned of for hours and therefore both temperatures are the same. Therefore printing temperatures may be offset by a few degrees as well.
